In a series RC circuit with an AC source R = 300Ω, C = 25 μF, ϵ0 = 50 V and v = 50/π Hz. Find the peak current and the average power dissipated in the circuit.

Given: Resistance (R) = 300Ω,

Capacitance (C) = 25 μF =,


Rms voltage (ϵ0) = 50 V and


Frequency (v) = 50/π Hz.


Then, Reactance will be





Now, Impedance (Z) will be






So, Peak current will be




And average power dissipated will be
